Bøger i Few-Body Systems serien

It is apparent from the history of science, that few-body problems have an interdis ciplinary character. After quantising the hydrogen atom, they soon found that the textbook case of a three-body problem in atomic physics, the 3He-atom, did not yield to the Bohr-Sommerfeld quantisation methods.

The International Conference Mesons and Light Nuclei, organized by the Institute of Nuclear Physics (INP), Rez, was held during July 2 - 7, 1995 in small north Bohemian town Straz pod Ralskem.

Few-body resonances are in the frontiers of resonance studies. Very similar problems occur in atomic and molecular physics, nuclear physics and high-energy physics.This collection presents the state of the art of the studies of resonance states in these fields and demonstrates their common methodological aspects.

This study provides a review of the theoretical approaches employed to evaluate two-body photodisintegration of the deuteron at low and intermediate energies. It surveys all experiments concerning this process and compares experimental results with theoretical ones.

Contains invited and contributed talks presented at the 1st Asian-Pacific Conference on Few-Body Problems in Physics, held in Tokyo, August, 1999. The papers in the volume are grouped into the following categories: Atomic and Mesoscopic Systems; Few-Body Problems in Nuclear Astrophysics; Unstable Nuclei and Nuclear Cluster Systems; and others.

Because of the complicated subject and the scarce available literature proper introductions in the subject are tiresome. Discussions and private contacts make it possible for participants to touch quickly the peripheries of the subject in question, and new research work will be stimulated which otherwise could not be expected.

The subject of this year's conference, as of the six previous meetings, was again elementary particle physics. On the other hand, the proceBses of weak interactions, too, are not yet fully understood, especially when strong interactions intervene, as in the radiative corrections to weak decays. . . . . . . . . . . . . . . . . 185 . . . .

On the occasion of the 50th anniversary of the discovery of the Schrodinger equation a small symposium was organized in Vienna. With their help this volume should become a useful document on the current mathematical art in the treatment of the Schrodinger equation.

Soluble quantum field theory models are a rare commodity. Yet, the models successfully studied in this way do DQ~ have an infinite field strength renormalization, which, at least according to perturbation theory, should appear for realistic relativistic models in four-dimensional space time.

The Boltzmann equation still forms the basis of the kinetic theory of gases and has proved fruitful not only for the classical gases Boltzmann had in mind, but als- if properly generalized - for the electron gas in a solid and the excitation gas in a superfluid.
